Anterior Lumbar Interbody Fusion (ALIF)

Definition

Anterior lumbar interbody fusion is a surgical procedure done through the abdomen to remove a diseased intervertebral disc and replace it with a spacer, thus restoring the disc height, decompressing the nerves, correcting deformity and fusing the vertebrae together in the corrected position.  

 

Indications

Three main indications for ALIF:

  • Degenerative disc disease causing disc collapse with compression of the nerves and back pain
  • Spondylolisthesis, which is instability between the spine bones, when two vertebrae shift next to each other
  • Recurrent disc herniation

  • Restore height of the disc space and remove pressure from the surrounding nerves
  • Correct alignment of the bones
  • Remove abnormal movement by fusing the bones together
